Hello. The gnat, libxmlada, gprbuild, dh-ada-library, libgtkada, libgnatcoll and libtemplates-parser packages require only trivial changes to build and pass run time tests in experimental with gnat-7. So libgpr probably replaces libgnatprj and fixes the project lookup path issue.
However, libasis still consumes the GCC sources exposed by libgnatvsn. The gcc patch should be updated to produce only libgnatvsn, not fully removed. The whole story, including an overoptimistic status: https://lists.debian.org/debian-ada/2016/10/msg00000.html https://lists.debian.org/debian-ada/2016/11/msg00000.html https://lists.debian.org/debian-ada/2017/01/msg00000.html https://lists.debian.org/debian-ada/2017/02/msg00001.html
